Halloween is just around the corner, I thought I’d create a theme that uses Halloween colors and icons… unfortunately there aren’t many spooky icons (spiders, pumpkins, death, gravestones, RIP…etc) available… I used what I can 
halloween:
# orange: dd5800; black: 000000; white: ffffff; coffee: 7a4901

divider-color: "rgba(255, 0, 0, 0.12)"
paper-card-background-color: "#000000"
paper-grey-200: "#4e4e4e"
paper-item-icon-color: "#FFFFFF"
paper-listbox-background-color: "#202020"
paper-listbox-color: "#FFFFFF"

make sure you put the following in your customize_glob.yaml file:
'zwave.*':
icon: mdi:skull
'alarm_control_panel.*':

'camera.*':

and refer to your customize_glob.yaml file in your configuration.yaml (see https://github.com/skalavala/smarthome/blob/master/configuration.yaml#L14 )
Feel free to use wildcards and add other domains and customize to your heart’s content. Happy Halloween!
